Which of the following is a requirement for masonry wall construction related to access zones?

In masonry wall construction, establishing access zones is crucial for ensuring worker safety. One of the key requirements is that the access zone must be at least the height of the wall being constructed. This requirement is designed to protect workers from potential hazards such as falling materials and debris that might occur during the construction process. By ensuring that the access zone reaches the full height of the wall, workers can safeguard against impacts from items that could fall from the top of the wall.

The importance of this minimum height requirement cannot be overstated as it serves to create a buffer zone, reducing the risk of falls or injuries. It reflects the principles outlined in OSHA standards that aim to maintain safe working conditions, particularly in environments where heavy materials and equipment are involved.
